I can't remember if this is my first post here or not! I'm ready to hit tire rack up for some GT500 wheels but really stressing about the tires. I know they recommend 255/45-18 but they look too skinny for the wheel to me. I found these Bridgestone Potenza RE960AS Pole Position in 275/40-18. They are all season but look pretty tight in the close up pics and the recommended rim width is 9.5 so they should be perfect. Does anyone have any pics of a setup like this?? Thanks!
